And now, the 2016 Olympic bids

Today is the day for the cities hoping to host the 2016 Olympics to submit their bids to the International Olympic Committee. The four cities are Chicago, Tokyo, Madrid and Rio de Janeiro.

Chicago is regarded by some to be the front-runner. In recent months, Chicago boosters have been traveling all over the Midwest, suggesting that Milwaukee, Madison, St. Louis and other areas might be areas where competition will be staged.
